New Diesel Engines for Sale — All Makes & Applications
Brand new diesel engines sourced from authorised channels with full OEM warranty. For applications where new is the only option — zero-compromise replacement, regulatory compliance, or maximum service life from day one.
New diesel engines are the right choice when specification cannot be compromised — when the application demands OEM-standard performance from the first hour, when regulatory or insurance requirements specify a new unit, or when the total cost of ownership over a long service life makes new the more economical option.
Commercial Engines sources new diesel engines across all major commercial brands. We supply new engines for commercial vehicles, agricultural machinery, marine applications, power generation, plant and construction, and industrial use. Call us with your engine code or application and we'll confirm availability, give you a lead time, and fix a price the same day.
When New Is the Right Answer
For most commercial diesel engine applications, a quality reconditioned engine delivers excellent reliability at significantly lower cost. But new engines are the clear choice in specific situations: applications where downtime cannot be risked over a long service horizon, machinery covered by manufacturer warranty programmes, or regulated industries where new certification is required.
We'll always give you an honest assessment of whether new, reconditioned, or remanufactured best suits your situation — we're not incentivised to upsell you to a new engine if a reconditioned unit will serve you just as well.
- OEM manufacturer warranty from day one
- Full compliance with regulatory or insurance requirements
- Maximum service life — the engine starts at zero hours
- Sourced and delivered UK-wide with fixed pricing
New Engines for Marine Applications
The marine engine market has specific sourcing requirements — marinised configurations, heat exchanger cooling, correct shaft output ratings, and certification compliance. We supply new marine diesel engines from Yanmar, Volvo Penta, Cummins, and Beta Marine across the full range of commercial and leisure marine applications. If you need a new inboard for a fishing vessel, workboat, or canal boat, we can confirm availability and arrange harbourside delivery.
New Engines Across Every Major Brand
We supply new diesel engines from the full range of leading manufacturers. Whether you need a new Cummins ISBe for an HGV replacement, a new Perkins 1106 for agricultural machinery, a new Yanmar for a marine application, or a new CAT unit for plant equipment, we can source and supply.
Lead times vary by manufacturer and model. We'll give you an accurate lead time when you enquire, and we'll fix the price at the time of order so there are no surprises when the engine arrives.
- Cummins — commercial, marine, and generator range
- Perkins — agricultural, industrial, and plant
- Yanmar — compact diesel, marine, and agricultural
- Volvo Penta — marine inboard and industrial range
New Engines for Power Generation
Standby and prime power generator sets require engines certified for generator application — specific speed rating, fuel system configuration, and emissions compliance. We supply new generator diesel engines from Perkins, Cummins, and other manufacturers certified for genset use. Whether you need a new engine for a critical data centre UPS or a site power genset, we'll confirm the correct specification and supply with full documentation.
New vs Reconditioned vs Remanufactured
Choosing correctly saves time and money — here's the honest picture.
| Option | Cost | Warranty | Condition | Best Application |
|---|---|---|---|---|
| New | Highest | OEM warranty | Zero hours | Regulatory compliance, max service life |
| Remanufactured | Mid-high | 12–24 months P&L | OEM-spec tolerances | High-value assets, high-duty cycles |
| Reconditioned | Mid-range | 12 months P&L | Working spec | Most commercial applications |
| Used | Lowest | 3 months | Inspected & tested | Budget-first, lower-value assets |
*We'll always recommend the option that genuinely suits your situation — not the most expensive one.
